Isnt there a PTU that lives in the forward horizontal stab compartment in the ceiling area and is used as a backup supply for running Stab trim in a loss of one/two Hydraulic systems (not sure of config)
I am sure I will be corrected if I am wrong
Yes this is the Pitch Enhancement System PTU. With loss of Left and Centre system pressure it transfers Right system pressure to the Left Stab Trim Motor. AMM 29-22-00
